BACKGROUND OF THE INVENTION

The electrical wiring in a structure is protected from moisture, flammable gas, chemical vapors, impact, and the like by being placed in electrical conduit. Electrical conduit has many diameters and is typically made from metal (e.g., steel, aluminum, etc.) or plastics (e.g., polyvinyl chloride (PVC), etc.). Local building codes and the U.S. National Electrical Code (NEC) specify the form and installation details for electrical conduit.

Current conduit systems, however, are cumbersome to install and require the use of tools. What is needed is a simple and fast method of protecting wires traveling through studs or installing complete systems of electrical conduit without the use of tools.

The present invention provides a stud wire protector. The stud wire protector includes: a first hollow cylindrical and a second hollow cylindrical member. Methods of inserting the stud wire protector are also provided.

The present invention also provides an electrical conduit coupling system. The electrical conduit coupling system includes: two or more stud wire protectors and two or more conduit couplers. Methods of attaching the electrical conduit coupling system to two or more studs are also provided.

The stud wire protector provides protection of the wires passing therein from external damage from nails, screws, drills, and the like to prevent potential arc fault conditions. It provides a smooth surface to ease the process of pulling wire through which also protects wire from scrapes during the installation process.

FIGS. 1-3 are perspective drawing illustrating an exemplary electrical conduit coupling system 100. The electrical conduit coupling system 100 includes: two stud wire protectors 101 and two conduit couplers 102. The two stud wire protectors 101 are configured to extend through and not beyond the side of a stud 104. The two conduit couplers 102 each have a proximal end that is configured to accept both ends of the stud wire protectors 101. The distal end of the two conduit couplers 102 are configured with an internal cavity to accept a spring 105 followed by an end of electrical conduit 103.

To assemble the electrical conduit coupling system 100, the springs 105 are inserted into each of the cavities in the distal end of each of the two conduit couplers 102. The ends of a pre-cut piece of electrical conduit 103 are inserted into each of the two conduit couplers 102 containing springs 105 to provide a conduit assembly. Finally, the conduit assembly is compressed by the user (not shown) and each end is inserted into the ends of the wall fittings 101 in the studs 104. Once the conduit assembly is in place, the user (not shown) releases the tension on the conduit assembly and the conduit assembly fits snuggly into place. This process is continued until the electrical conduit for the room is in place. At that time, the electrical wires are inserted into the conduit.

To disassemble the electrical conduit coupling system 100, the user (not shown) compresses the conduit assembly, removes the conduit assembly from the structure, compresses the press-fitting on the proximal end of each of the wall fittings 101, and removes the wall fittings 101 from the studs 104.

FIG. 4 is a perspective drawing illustrating an exemplary stud wire protector 101 and studs 104 that contain pre-drilled holes 106. The wall fittings 101 are inserted with pressure into the pre-drilled holes 106 in the studs 104 so that both ends of the wall fittings 101 protrude from the surface of the studs 104.

FIGS. 5-8 are drawings illustrating an exemplary stud wire protector 101 that includes a first hollow cylindrical member 107 and a second hollow cylindrical member 108. The first hollow cylindrical member 107 is a tubular sleeve that has a length less than or equal to the width of a stud in which the stud wire protector is to be used. In a residential setting using balloon wall construction uses 2″×4″ studs which in reality are 1.5″ in width. In many commercial settings the studs used are the same width. In other commercial settings metal studs are employed which may have a different width dimension. It is to be understood that the length of the tubular sleeve 107 can be any dimension so that in application the length of the tubular sleeve is about equal to the width of the stud used in wall construction.

In other words, the first hollow cylindrical member or sleeve 107 has a length substantially equal to the width of a stud into which it will be placed. In some applications, it may be necessary to protect against nail penetration across a pair of studs. In this case the first hollow cylindrical member or sleeve 107 has a length substantially equal to the width of a pair of studs. It should be understood the first hollow cylindrical member or sleeve 107 can have a number of different lengths and that in most instances the length will be related to the width of a stud (1.5 inches) or a multiple thereof. The most common length of the sleeve 107 will be for the width of a single stud since this is the most common in frame construction for residences and some commercial buildings. The sleeve also has an inner diameter that will allow wire to pass within the sleeve. The sleeve has an outer diameter smaller than that associated with an opening in a common stud. In that way, the sleeve 107 and the wire protector 107 fit within the stud.

The first hollow cylindrical member or sleeve 107 is made of a material that will resist or prevent a nail or other fastener from penetrating the sleeve. The sleeve can be made of steel of sufficient thickness to stop a fastener either being pounded or screwed into a stud with a hammer or screwdriver, or to stop a nail from a nail gun. The first hollow cylindrical member 107 has a proximal end, a distal end, and is configured to extend through and not beyond a stud (not shown). The material, in one embodiment, has a Rockwell hardness index value in the range of 120-200. In another embodiment, the Rockwell hardness index value in the range of 140-180. In still a further embodiment, the Rockwell hardness index value in the range of 150-170. In another embodiment, the Rockwell hardness index value in the range of 157-164.

The material forming the sleeve must be sufficiently hard to resist penetration from various fasteners that might be placed into the formed wall at a later time. It should also be noted that the material can not be brittle such that it would crack when a sharp end of the fastener contacted the sleeve. Materials contemplated are galvanized steel, steel, stainless steel, ceramics, composite materials, and the like. Metals may be heat treated in various ways to provide a hard, exterior surface.

The hole in the stud can also be placed so that it is at a uniform distance above the floor or the bottom plate of a stud wall. The hole in the stud can also be placed at a uniform distance set back from the front face of the stud. These dimensions could be part of a building code or could be within a range set by a building code. In one embodiment, a jig is provided so that the openings in the studs of a wall frame are substantially uniform. In this case, the holes or openings in the studs would be substantially aligned so that pulling wire through the openings could be done with less effort.

The second hollow cylindrical member 108 has a first fitting 109 at a proximal end and a second fitting 110 at a distal end. The second hollow cylindrical member 108 is configured to fit within the first hollow cylindrical member or sleeve 107. The first fitting 109 is configured to insert within and to extend beyond the proximal end of the first hollow cylindrical member or sleeve 107. The second fitting 110 is configured to extend beyond distal end of the first hollow cylindrical member 107 when the second hollow cylindrical member 108 is inserted into the first hollow cylindrical member 107 or sleeve.

In one embodiment, the first fitting 109 is a press-fitting. In one embodiment, the press-fitting is a tapered press-fitting as shown. In one embodiment, the second fitting 110 is a tapered fitting as shown. In the embodiment shown, the second hollow cylindrical member 108 has a substantially tubular body. The ends of the substantially tubular body carry the first fitting 109 and the second fitting 110. The outside diameter of the second hollow cylindrical member 108 is substantially equal to the inner diameter of the sleeve 107. Generally, the outside diameter of the second hollow cylindrical member 108 is slightly less the inner diameter of the sleeve 107 to allow for easy assembly of the sleeve and second hollow cylindrical member 108. The second fitting 110 has a substantially tubular body with an outside diameter that allows the second fitting to fit within the inner diameter of the sleeve 107. At each end of the substantially tubular body of the second fitting is a flange. The flange has a rim with an outside diameter greater than the diameter of the first hollow cylindrical member or sleeve 107. The flange outside diameter of each flange of the second fitting is also greater than the diameter of the opening or hole in the stud into which it will be placed. In one embodiment, the second hollow cylindrical member 108 has an end with one or more indentations 111 that extend from the proximal end toward the interior to allow for the proximal end of the second hollow cylindrical member 108 to contract when the second hollow cylindrical member 108 is inserted into the first hollow cylindrical member 107. The indentations or slots 111 in the flange as well as the main body form flexible fingers which comprise the second fitting 108. The fingers are between the indentations 111 or slits. The second hollow cylindrical member 108 is made of a material that will allow the fingers formed to move through an elastic range so that the fingers can bend when inserted into a hole or opining within a stud and then return to an original position without plastic deformation. The stud wire protector 101 can then pass through the opening and snap or lock into a position when the fingers formed snap back to their original position. In other words, the slotted or indented end is also inserted into an opening or hole in a stud. As the end is inserted, the fingers bend elastically so that the flange on that end can pass through the opening. The fingers bounce back and return to the original position upon passing through the opening in the stud. This locks the stud wire protector 101 into place as the stud is captured between the slotted flange end and the solid flange end of the stud wire protector 101.

The wire protector 101 can be removed from the stud by pressing the fingers inwardly until the fingers are at a smaller diameter than the opening or hole in the stud. The wire protector 101 can then be moved so that the fingers are touching the inner wall of the opening. These can then be moved further until the wire protector is out of the opening in the stud.

FIGS. 9-13 are various drawings illustrating an exemplary conduit coupler 102.

The conduit coupler 102 includes a tapered internal cavity 112 at the proximal end that accepts a tapered exterior of the first fitting 109 and the second fitting 110 that are contained in the wall fittings 101. In other words, the conduit coupler 102 includes a tapered cavity 112 shaped to receive one or both of the flanged ends of the stud wire protector 101. In this case, the stud wire protector 101 is positioned in an opening in a stud in a framed up wall. In one embodiment, the conduit coupler 102 includes a circular cavity 113 at the distal end that accepts a spring 106 and an end of electrical conduit 103.

In step 203, the user inserts each end of a piece of electrical conduit into each of the two conduit couplers. Finally, in step 204, the user attaches each end of the electrical conduit assembly to the two stud wire protectors.

FIG. 17 is a front view of an electrical box 1500, according to an example embodiment. FIG. 15 is a first side view of an electrical box 1500, according to an example embodiment. FIG. 16 is a second side view of an electrical box 1500, according to an example embodiment. FIG. 16 also includes a partial cross-sectional view portion corresponding to cutline A-A in FIG. 17. Now referring to FIGS. 15-17, the electrical box 1500 will be further detailed. An electrical box 1500 includes a first side 1510 and a second side 1520. The first side 1510 has a cut out 1512 therein. The second side 1520 includes a first ridge 1521 and a second ridge 1522. Both the first ridge 1521 and the second ridge 1522 are on the exterior portion of the second side 1520. The first ridge 1521 is substantially parallel to the second ridge 1522. The first ridge 1521 and the second ridge 1522 are spaced apart from one another at a distance d substantially equal to the distance d between the two sides of the cut out 1512.

The first side 1510 has at least one locking tab 1514 positioned near one edge of the cut out 1512. The second side 1520 has at least one slit 1524 sized to receive a locking tab 1514 like the at least one locking tab 1514 on the first side 1510. In another embodiment, the first side 1510 of the electrical box has a plurality of locking tabs positioned near an edge of the cut out near a back of the electrical box, and the second side of the electrical box has a plurality of slits positioned for receiving the plurality of locking tabs.

It should be understood, that electrical box 1500 can be used alone or with another substantially similar electrical box.

FIG. 18 is a perspective view of box 1500 being attached to another similar box 1500′, according to an example embodiment. In the embodiment where at least two electrical boxes are connected, the first side 1510 of one electrical box 1500 is connected to the second side 1520′ of the other electrical box 1500′ to form a two-gang box. Additional boxes 1500 can be added to form a three-gang box, a four-gang box or box with “x” number gang box. The beauty of this design is that a contractor can carry just one style of box 1500 in inventory or on a truck. From the one style of box, a number of boxes 1500 can be assembled together to make various sizes of boxes with a desired number of gangs. An “x” gang box can be assembled from “x” number of boxes. So, a contractor does not have to carry three and four gang boxes on a service truck. Rather the contractor can form one from a number of the boxes 1500.

As shown in FIG. 17, the electrical box 1500 or insulative box also includes at least one punch plate 1530 (also shown in FIGS. 15 and 16) on one or more sides of the electrical box.

FIG. 20B is another perspective view of the box 1500 as assembled with the box mount bracket 1910, mounting tube or mounting tube assembly 1950, and slide bracket 1940.

Most generally, the electrical box system can be thought of as including a base electrical box, and an end portion. The end portion is added to the base electrical box to substantially complete the electrical box. In some embodiments, the electrical box includes at least one intermediate portion that is added to complete the electrical box. The at least one intermediate portion, in some embodiments, is placed between the base electric box and the end portion which is added to the electrical box. In some embodiments, the intermediate portion is placed between the base electrical box and the end portion. In some embodiments, the intermediate portion is placed after the end portion has been attached to the base. In other embodiments, the intermediate portion is added or attached to the base before the end portion is added to complete the electrical box. In some embodiments, there can be one or more intermediate portions that do not directly connect to the base or the end portion. The box is literally built to size out in the field. In some embodiments, the resulting box has a size to accommodate a single gang electrical component. In other embodiments, the resulting box has a size to accommodate a plurality of single gang electrical components. This is generally referred to as a multiple gang box or a 2 gang, 3 gang, 4 gang, etc. sized electrical box. In another embodiment, at least some of the intermediate portions are substantially identical parts. In still further embodiments, at least one or some of the intermediate portions are substantially identical to the base electrical box.

Various embodiments are detailed as discussed and illustrated in FIGS. 17-20A Yet another embodiment of such as system is shown in FIGS. 32-34. FIG. 32 is a perspective view of an alternative box 3210 or base, and an end portion 3220, according to an example embodiment. FIG. 33 is a perspective view of an alternative box 3210 and an intermediate portion 3300, according to an example embodiment. FIG. 34 is perspective view of an alternative box 3210, a plurality of intermediate portions 3300 and an end portion 3220 assembled into a multiple gang electrical box 3400, according to an example embodiment. In this embodiment, a multiple gang box can be custom made from a base or alternative box 3210, any number of intermediate portions 3300 and an end portion 3220. The intermediate portions 3300 are fit to the base or alternate box 3210 and to one another to form the multiple gang box 3400 shown in FIG. 34. This is similar to the previously discussed system. Among the differences is that the intermediate portion 3300 differs from the base or alternative box portion 3210. This system also allows the construction person to construct boxes from fewer parts and therefore allows the person in the field to have to carry fewer parts when compared to carry a number of various gang number boxes. The embodiment detailed in FIGS. 17-20A has the advantage that the base box and the intermediate part is substantially similar or the same.

FIG. 21 is a perspective view of an electrical box 2100 for accommodating at least two duplex electrical outlets, according to an example embodiment.

The base is attached to a structural element in the absence of electrical wire. This lessens the chance that the electrical wire might be damaged.

The tie 2700 for holding electrical wire (not shown) includes a base engaging portion 2710 and a wire or multiwire engaging portion 2712. The wire engaging portion 2712 has a length substantially equal to the circumference of the wire or multiple wire package used in wiring. One example of multiwire package is Romex. Several wires are included and wrapped in a sheath of thin, flexible material. The base 2900 includes a tie opening 2922 therein. The zip tie 2700 is adapted to hold wire, such as Romex wire with the wire engaging portion 2712. Put another way, the zip tie 2700 further includes a first portion 2712 having a first width, and a second portion 2710 having a second width lesser than the first width. The tie opening 2922 in the base 2900 is sufficient to allow the second portion 2710 of the tie 2700 to pass therethrough, but too small to allow the first portion 2712 of the tie 2700 to pass therethrough. The tie 2700 also includes a connector 2732 on the free end 2734 of the first portion 2712 sized to receive the second portion 2710 of the tie 2700. The connector 2732 includes a pawl like extension or pawl like teeth internal to the connector 2732. The zip tie 2700 includes a plurality of ridges 2740 that engage the pawl like teeth in the connector 2732. The pawl like portion of the connector engages at least one of the plurality of ridges 2740. The ridges 2740 run substantially down the length of the zip tie 2700, in one embodiment. At least the second portion 2710 includes a plurality of ridges transverse to the length of the second portion. In other words, the ridges cross the width of at least the second portion 2710 of the zip tie 2700. Put another way, the connector includes a ratcheting mechanism for attaching to at least one of the plurality of ridges on the second portion 2710 of the tie 2700. The first portion 2712 of the tie has a length substantially equal to the outside circumference of the electrical wire. In this way, the outer portion of the wire may be more fully supported by the increased width. The fastener or connector in the base 2910, in one embodiment is a screw. In another embodiment, the fastener is a sheet metal screw that can be used in wooden studs, commonly used in residential building, and that can be used in metal studs, more commonly used in commercial building. The fastener can be retained with the tie 2700, in some embodiments. In this way, a user does not need to find a separate fastener when picking up a tie 2700 to use. This saves time during installation and routing of wires, such as romex style wire. In one embodiment, a screw which is installed in the fastener opening 2712 so that the screw can be turned during installation and will not fall out. More specifically, the screw has an unthreaded portion near the head of the screw. The unthreaded portion has a length or width slightly more than the thickness of the base 2710. With an unthreaded portion of a length or width slightly more than the thickness of the base, the screw can turn freely while being held within the opening. The screw head and the threads retain the screw, in one embodiment.

FIG. 31 is a flow diagram of a method for holding an electrical conductor, according to an example embodiment. The method 3100 for holding an electrical conductor includes defining a path for the electrical conductor 3110, attaching a first zip tie along the path 3112, and attaching a second zip tie 3114 at another position along the defined path. It should be noted that the path does not have to be followed exactly or precisely. The method 3100 also includes placing an electrical conductor near the first zip tie 3116 and zipping the first zip 3118 tie to hold the electrical conductor. Another portion of the electrical conductor is placed near the second zip tie 3120 and zipped to the second zip tie 3122 to hold the other portion of the electrical conductor. The path can include a plurality of these types of ties. The zip tie is attached before the wire is attached. In other words, attaching the device to a structure is done without having the wire nearby. This reduces the chance of failure caused by striking the conductor inadvertently during installation. In prior art methods, a staple like device holding two nails is placed over the Romex wire and then the nails are pounded into place. A slip of the hammer can damage the internal wires.

The first zip tie includes a fastener portion for receiving and retaining a fastener. Similarly, the second zip tie also includes a fastener portion for receiving and retaining a fastener. The fastener can be a nail or a screw or the like. In one embodiment, the fastener is a sheet metal screw. The sheet metal screw can be used to attach to various building materials, such as wood used in residential applications and metal more commonly used in commercial applications. Attaching the first zip tie along the path includes placing the fastener portion on a structure and turning the screw. Similarly, attaching the second zip tie along the path includes placing the fastener portion on a structure and turning the screw. The zip ties have a narrow width associated with the fastener portion and a wide width associated with the portion for holding the electrical conductor. The wider portion distributes the force over a larger area and lessens the possibility that one conductor with insulation might be forced into electrical contact with another conductor. The wider portion cradles the electrical wire or electrical wires. For example, in a Romex type conductor which holds three conductors (positive, negative and ground), the conductors are cradled with a lesser pressure since the force is distributed over a larger area. This provides for a safer installation of the wire set.

A system for holding an electrical conductor (not shown) includes a first base 2900 attached to a structure, and a second base 2900 attached to the structure. The first and second bases 2900 are attached along a path for an electrical conductor. Both the first and second bases receive the narrow portion 2710 of the zip ties 2700. This leaves the wider portion 2712 open to receive the electrical conductor. The electrical conductor is attached to the bases 2900 after being attached to the structure. In other words, when the electrical conductor is attached the structure, the wide portion 2712 of the zip ties 2700 are open so that the electrical conductor can be received or cradled therein. Once the electrical conductor is placed in the first and second zip tie 2700, and zipped, a first electrical conductor portion is held by the first zip tie 2700, and a second electrical conductor portion held by the second zip tie 2700. The first zip tie 2910 has a first width and a second width. The first width is narrower than the second width and used to attach the first zip tie 2700 to the first base attachment portion. The second width having a length substantially equal to the circumference of the electrical conductor. The electrical conductor (not shown), in one embodiment, includes at least two wires. In another embodiment, the electrical conductor includes three insulated wires covered by a sheath. Such a conductor is available as Romex wiring and is commonly used when wiring in residential construction. In commercial applications the sheath is a cable.

In the claims provided herein, the steps specified to be taken in a claimed method or process may be carried out in any order without departing from the principles of the invention, except when a temporal or operational sequence is explicitly defined by claim language. Recitation in a claim to the effect that first a step is performed, then several other steps are performed, shall be taken to mean that the first step is performed before any of the other steps, but the other steps may be performed in any sequence unless a sequence is further specified within the other steps. For example, claim elements that recite “first A, then B, C, and D, and lastly E” shall be construed to mean step A must be first, step E must be last but steps B, C, and D may be carried out in my sequence between steps A and E and the process of that sequence will still fall within the four corners of the claim.

Furthermore, in the claims provided herein, specified steps may be carried out concurrently unless explicit claim language requires that they be carried out separately or as parts of different processing operations. For example, a claimed step of doing X and a claimed step of doing Y may be conducted simultaneously within a single operation, and the resulting process will be covered by the claim. Thus, a step of doing X, a step of doing Y, and a step of doing Z may be conducted simultaneously within a single process step, or in two separate process steps, or in three separate process steps, and that process will still fall within the four corners of a claim that recites those three steps.

Similarly, except as explicitly required by claim language, a single substance or component may meet more than a single functional requirement, provided that the single substance or component fulfills the more than one functional requirement as specified by claim language.
